We propose developing a diode laser-based full-spectrum Raman scattering instrument prototype incorporating fiberoptic coupling for rapid, continuous on-line and remote monitoring of fuels. Raman's narrow, well-defined peaks and its insensitivity to moisture contamination allow for full-spectrum… More

We propose to determine the feasibility of using diode-laser-based, full-spectrum Raman scattering technology incorporating fiber-optic coupling for rapid, continuous, on-line detection and monitoring of key intravenous (IV) drugs. Raman's narrow, well-defined peaks and insensitivity to water… More

We propose to develop intermediate to high power (.1 to 4 W), frequency- stable diode lasers with high modulation capability and long life. Our approach can provide fixed-frequency radiation sources for 1 pace-based ballistic missile defense applications. To demonstrate the technology we will… More

We propose developing a compact, optical fiber-based Raman scattering instrument for rapid, in-situ analysis of composites, solid rocket motors, and propellants. The instrument will incorporate diode laser-based, full-spectrum Raman scattering forcontinuous in-situ remote monitoring of the… More

We propose developing a compact, optical fiber-based Raman scattering instrument for rapid, in-situ health monitoring and analysis of solid rocket motors and propellants relied on for the Ground-based Midcourse Defense (GMD) program. The instrument willincorporate diode laser-based, full-spectrum… More

78230S In the production of gasoline, refineries currently monitor acid strength via titration techniques once or twice per shift, which results in running higher-than-optimal acid concentrations to ensure that the process proceeds uninterrupted. This project will develop a reliable in situ method… More

A need exists for a reliable, non-destructive, in-situ method to monitor the chemistry of solid rocket motor propellant to determine its health and stability during the service life of the motor. Ideally, the sensor would be able to monitor the chemical components of the motor and not affect the… More

The removal of sulfur and CO2 from hydrocarbon streams and power plant effluents is a major problem. Because the sulfur is normally in the form of H2S, this acid gas is scrubbed using aqueous amine solutions that are difficult to control with conventional technology. CO2 scrubbing may soon be… More
